The team has expressed interest in re-signing the veteran, a league source said Monday. Where contract negotiations stand is not known, but Franklin will become an unrestricted free agent if no deal is signed before Tuesday at 1 p.m. PT.

Franklin, 32, spent 2011 in the Saints' 4-3 scheme.

The style didn't play to the run stopper's strengths, and he looked more comfortable absorbing double teams under Chargers defensive coordinator John Pagano's 3-4 system.

Franklin started nine of 12 games, finishing with 20 tackles.

Cam Thomas and Antonio Garay were the other nose tackles on last season's roster. Both are under contract for 2013. Garay, due a $1.5 million roster bonus and $3.5 million base salary, is considered a likely cap casualty.
